Hypoparathyroidism

Dr Daniel J Bell and Dr Henry Knipe et al.

Hypoparathyroidism results from reduced secretion of parathyroid hormone by the parathyroid glands. It results in hypocalcemia. 

  • tetany: peripheral paresthaesia, carpopedal spasm, seizures
  • emotional lability, depression and anxiety, psychosis
  • short stature

There are a number of causes of hypoparathyroidism 1:

  • iatrogenic, e.g. post parathyroidectomy or thyroidectomy
  • congenital absence of the parathyroid glands, which may be syndromic in thymic aplasia, or 22q11.2 deletion syndrome (a.k.a. DiGeorge syndrome)
  • familial, e.g. autoimmune polyendocrine syndrome type 1
  • idiopathic (probably autoimmune-mediated destruction)
  • parathyroid hormone (PTH) level: low
  • serum phosphate level: high
  • serum calcium level: low
